BUCK ANCHOR.

Application filed November 28, 1823. Serial No. 677,405.

T 0 all 107107 it may concern:

Be it known that we, TAMIS C. SCHENK and PETER GOl IBERT, citizens ofthe United States, and residents of Bridgcville and Pittsburgh,respectively, in the county of Allegheny and State of Pennsylvania, haveinvented a new and useful Improvement in Buck Anchors, of which thefollowing is a specification.

This invention relates to building construction, and particularly tobuck anchors for rigidly securing door frames to walls formed of hollowblocks or tiles.

One of the most common methods of at taching the side members orso-called bucks of door frames to partitions built up ofterra-cottablocks or tiles is to drive nails into or through the bucltsso as to provide projections which may be either embedded in the cementbetween the superposed courses of the blocks or tiles, or which in someinstances are embedded in the blocks themselves. hen the former schemeis used, the nails are generally driven part-way into the faces thereofadjacent the blocks so that their projecting heads may extend betweenthe courses to be, embedded as described, whereas when the latter schemeis adopted the nails are driven directly through the bucks so as toenter the cement forming the bonding layer or directly into the body ofthe blocks if the same are of such nature as to permit this practice.Both of these methods are open to various objections not only because ofthe difiiculties attending i11 spe'ction but because the nails readilyloosed, jar out, and loosen their anchoring or bind ing effect.Furthermore, the subsequent nailing of the plaster supporting means, thejamb, and the trims tends to destroy or weaken the attached parts. It isalso well known that such methods are entirely unsuited for attachingbucks close to and spaced from partition walls under which circumstancesthe buck can not be supported directly from the partition wall, andthis'is particularly noticeable when it is desired to so positionthe-bucks and at the same time provide a full trim.

The object of this invention is to provide an extremely simple,inexpensive and easily applied buck anchor which will overcome thedisadvantages above noted, which will positively and firmly lock thebuck directly to the partition wall and hold'it against both transverseand longitudinal movement relative thereto.

It is a special object to provide a buck anchor of the characterreferred to which is adapted for use under avariety of conditions and bywhich bucks may be readily and directly anchored to the partition wallregardless whether the buck is positioned at the end or side of thepartition, or whether it is disposed in contact therewith or spacedtherefrom.

It is also a special object to provide a buck anchor which is adapted tosupport the buck at any desired angle relative to the partition wall towhich it is fixed, and which engages the tiles of the wall in suchfashion as to obviate the danger of either transverse or longitudinalmovement of the buck.

These and other objects will more fully appear when taken in conjunctionwith the following description and appended claims.

In the accompanying drawings, Fig. 1 is a fragmentary view, inperspective, illustrating the use of the invention for supporting a buckat the end of the partition wall and in alignment therewith, the layeror course of tiles immediately above the anchor being removed so as toclearly show the mode of engagement between the anchor and the walls ofthe tile; Fig. 2 a similar view illustrating the method of supportingthe buck at the side of the partition wall contiguous the end thereof;Fig.3 a similar view showing the method of usingthe invention forsupporting the buck at the side of the partition wall, at right anglesthereto, and spaced there from; Fig. 4 a view corresponding to Fig. 3 inwhich the buck is disposed at an angle to the partition wall; and Fig. 5an enlarged detailed perspective view of the buck anchor removed.

' The improved buck anchor is preferablywith suitable openings 4 adaptedto receive nails or screws tor attaching the buck to the anchor. Thesefingers are comparatively wide at their point of connection with thebody for the purpose of increasing the strength of the anchor, butgradually decrease in size towards their tips or extremities. Theextremities of the fingers are bent (hiwnwardly as shown at 5, theseextremities lying in a plane substantially parallel to that occupied bythe body 1.

The distance between the side of the body and the inner surface of theextremities corresponds to the wall thickness of the hollow blocks ortiles with which the anchor is to be used, and the distance between theadjacent extremities 5 corresponds to the thickness of the internaltransverse webs joining the side walls of the tiles.

In all of the figures of the drawings, the hollow blocks or tiles areindicated at 6 and for simplicity merely two superposed layers formingthe partition wall are illustrated. The extremities 5 are spaced fromthe body a distance corresponding to the thickness of the side wall 6,and the tips of adjacent fingers are likewise spaced a distancecorresponding to the thickness of the transverse webs 6, as described.Due to this construe tion when the anchor o ieratively engaged with thewalls of the tile. with the lingers 2 interposed between the courses ofblocks, the side walls 6 are snugly embraced between the body 1 and thebent extremities 5 so as to avoid relative lateral movement of theanchor, and similarly when the anchor is positioned. so that thetransverse wall 6" falls between two adjacent fingers, the anchor ispositively locked against longitudinal movement.

In operation. the anchor described lends itself to a variety of usesunder varying conditions, in each instance, however, supporting the buckdirecth from the partition wall with which it is associated. andexerting the stresses and strains due to the attachment of the buck in aaight line pull.

In Fig. l. the anchor is employed for se curing the buck 7 at the end ofthe wall and in alignment therewith, the buck being interposed betweenthe extensions 3 of a pair of anchors attached to the opposite sidewalls of the tiles. and the anchors are fast ened to the buck by nailsor screws passed through the openings It is noted that due to the snugfit ot' the side walls 6 between the body 1 and the extremities 5 alldanger of lateral movement is eliminated, and due to the engagement ofthe fingers with the web 6. the buck is positively locked againstmovement away from the end of the wall.

The anchors are preferably used in pairs, as just described. in whichcase the fingers of the opposed anchors extend in opposite directionsfrom the bodies thereof, however, in many instances the employment ofbut a single anchor is necessary.

The method of using the improved anchor for securing a buck at the sideof the partition wall. immediately adjacent one end thereof isillustrated in. Fig. 2, in which the buck is shown at 7. In this case,the body of one anchor is bent as at 8 so as to abut the side of thebuck, while the opposed anchor is bent at 8 so as to engage the cornerof the end tile. Vith this arrangement the fingers and bodies of bothanchors separately and conjointly assistin preventing both transverseand longitudinal movement of the buck.

For the purpose of supporting the buck intern'iediate the length of thewall but spaced therefrom, and at right angles thereto, the method shownin Fig. 3 is employed, in which figure the buck is indicated at 7". Inorder to space the buck from. the partition wall a slab 9 of suitablesize is interposed between the wall and buck. The bodies of the anchorsare bent at 10, 10, with the fingers engaging the side walls of both thetile 6 and the slab 9. henever one of the fingers falls so as to overliethe abutting end walls 6 of contacting tiles, as illustrated in thisfigure, the said finger ,is flattened so that its extremity 5 projectsin the same plane as the finger, in the manner indicated at 11, Thefingers of both anchors assist in directly supporting the buck from thepartition wall and prevent movement of the buck away from the wall,while the pair of fingers straddling the web 6 preclude movement of thebuck longitudinally of the wall.

If it is desirable to locate the buck spaced at the side of thepartition wall and disposed at an angle thereto, the same may beaccompllSllQd by interposing a. slab 9 as illustrated in Fig. i. Thebuck 7 is in this instance directly supported from the partition wall ina manner similar to that pointed out in connection with Fig. 3, theseveral parts cooperating in an analogous way.

Both of the methods shown in Figs. 3 and are particularly adapted forsupporting bucks in closely spaced relation to the partition wall whileat the same time throwing the entire strains directly upon the wall in astraight line pull, and permitting full trim to be used in connectionwith the bucks.

It is thus seen that the invention provides an extremely simple andinexpensive form of buck anchor which is capable of directly supportingthe buck from the wall to which the anchor is attached, one which lendsitself to a variety of uses, being adapted to support the buck directlyfrom the wall regardless whether it is located at the side, at the end,in contact or spaced Ill) therefrom, and one which positively locks thesupported buck against both transverse and longitudinal movement withrespect to its supporting wall.
